How does it work?
  1. Memorize the sound of a letter (for example, "Q") and the position of a filled rectangle (for example, the top-left corner).
  2. At level N (Dual N-Back), press "Audio" when the sound is the same as the sound played N steps before and press "Visual" when the rectangle is at the same position as the rectangle N steps before.
  3. Example (3-Back, sound): G H T W H - "Audio", because "H" was also played 3 steps before.
Supported phones

The application supports nearly all current Nokia, Sony Ericsson and Samsung phones. There is a special version for BlackBerry smartphones and a version for Android phones.
